During January-March, Scotian Shelf water has been observed to flow episodically
from the southwestern Scotian Shelf directly across the Northeast Channel to Georges
Bank. The possible factors that allow Scotian Shelf ...

When ocean waves in deep water interact with a current, the direction of propagation
and characteristics of the waves such as height and length are affected. Swell in the open
ocean can undergo significant refraction as ...

The dynamical aspects involved in the assimilation of altimeter data in a
numerical ocean model have been investigated. The model used for this study
is a quasi-geostrophic model of the Gulf Stream region. The data that ...

Four different problems concerning Gulf Stream Rings are
considered. The first deals with the particle trajectories of, and
advection-diffusion by, a dynamic model of a Ring. It is found that the
streaklines computed ...

An investigation was carried out to observe the geologic effects of
steady bottom currents on sediments of East Katla Ridge on the southern
insular rise of Iceland. Near-bottom southwest to west-flowing currents
exceeded ...

This thesis explores the buoyancy-driven circulation in the Red Sea, using a combination of
observations, as well as numerical modeling and analytical method.
The first part of the thesis investigates the formation ...

In previous Gulf Stream work (Hall and Bryden, 1985,
Hall, 1985, 198GA, 198GB), a decomposition of multiple depth
current records was developed which produced along- and
cross-stream components. The cross-stream component ...

The development and application of an autonomous field instrumentation
system consisting of four current meters and four wave gauges, along
with a field monitor and digital recorder, is documented.
The flow sensors are ...

Observations of diapycnal mixing rates are examined and related to diapycnal
advection for both double-diffusive and turbulent regimes.
The role of double-diffusive mixing at the site of the North Atlantic Tracer ...

Data from the COBOLT experiment, which investigated the first 12 km
off Long Island's south shore, are analyzed and discussed. Moored current
meter records indicate that the nearshore flow field is strongly
polarized ...

This thesis presents an investigation of the dynamics of bottom boundary currents in the ocean. The major emphasis is to develop simple mathematical models in which various dynamical features of these complex geophysical ...

A state-of-the-art, high-resolution ocean general circulation model is used to estimate the time-dependent global ocean heat transport and investigate its dynamics.
The north-south heat transport is the prime manifestation ...

Mean long-isobath drift of the order 5 cm/sec has been observed on
several continental shelves, e.g. in the Middle Atlantic Bight and in the
Weddell Sea. A theoretical model is developed to explore the driving
mechanism ...

The transformation of potential vorticity within and stability of nonlinear deep
western boundary currents in an idealized tropical ocean are studied using a shallowwater
model.
Observational evidence indicates that the ...

Geosat altimeter data and numerical model output are used to examine the
circulation and dynamics of the Antarctic Circumpolar Current (ACC).
The mean sea surface height across the ACC has been reconstructed from
height ...

This study focuses on the zonal weakening, eastern termination and
seasonal variations of the Atlantic equatorial undercurrent (EUC). The
main and most original contribution of the dissertation is a detailed
analysis ...

The subtidal circulation of the southeast Greenland shelf is described using a set of highresolution
hydrographic and velocity transects occupied in summer 2004. The main
feature present is the East Greenland Coastal ...

This thesis addresses several aspects of the problem of determining the
effect of the low-frequency eddy variability on the mean circulation of the
Western North Atlantic. A framework for this study is first established ...

Rotating baroclinic and barotropic boundary currents flowing around a corner
in the laboratory were studied in order to discover the circumstances under which
eddies were produced at the corner. Such flows are reminiscent ...
